------- 060796 .A.V2zipan Patented July 25, 1944 UNITED STATES PATENT OFFICE SAW JOINTING DEVICE George A. Vaipan, Tyonek, Territory of Alaska Application July 8, 1942 Serial No. 450,167

1 Claim.

The invention relates to improvements in a combined saw jointing device.

The object of the invention is to provide a saw set in which some of the essential parts thereof are used as a guide for a saw as it is passed over a jointing file removably secured by means arranged in an extension of the rest portion of the base of the saw set.

Another object of the invention is to provide a simple and effective saw jointing device which can be cheaply manufactured and having certain details of structure and combination of parts hereinafter more fully set forth.

In the accompanying drawing- Figure 1 is a perspective view of a saw set with my improved jointing device formed as an integral part thereof.

Figure 2 is a top plan view of Figure 1.

Figure 3 is an end elevation of Figure 2.

Referring now to the drawing, l4 represents a base having a saw rest portion I6 adjacent its front edge. The front edge of the base, midway its ends, is provided with a downwardly extending lug l1, having a segmental tooth portion l8. Pivotally mounted on the lug II, by the pivot I9, is a lever 23, having at its outer end a foot portion 2!. The lever 20 is curved downwardly, as indicated at 22, and carries at its inner end a foot portion 23, which is preferably covered by some soft material, so as to engage more firmly the lower face of the table to which the device is to be attached. Intermediate the front and rear edges of the rest portion is a slot 24, in which is arranged an anvil member 30. The side edges of the base are provided with gauge bars 3| and 32, which are adjustable longitudinally and adapted to properly place the saw in respect to the anvil. The rear end of the base is provided with a vertical wall 33, to which is pivotally connected, at 34, the lever 35. The outer end of the lever is provided with a handle 36, and intermediate said handle and the pivot thereof is a socket 31 of rectangular form, in which is arranged a plunger 38, having at its lower end a beveled portion 39 adapted to set the tooth of the saw. The specific construction and arrangement of the clamping means and the tooth setting means form the subject-matter of separate applications executed of even date herewith.

The saw jointing means comprises a horizontally disposed plate 40, carried by the rear end of the base M, at one edge thereof. The plate 40 is looped at its outer end, as indicated at 4|, and extends forwardly to form a flat horizontal portion 42 parallel with the plate 40. The dis tance between the plate 40 and the portion 42 is of such a width that a flat file 43 may be readily inserted therein. The fiat horizontal portion 42 is provided with a vertically disposed set screw 44, which is adapted to engage the saw and firmly hold it against the rear Vertical wall of the base M. The inner end of the fiat portion is provided with a vertically disposed upwardly extending portion 45, which is spaced from and arranged parallel with the rear wall of the base. The portion 45 is spaced a distance from the wall of the base to allow a saw to be readily inserted therein. The vertical portion 45 is provided with a set screw 46, which is adapted to engage the saw and properly guide the same. The set screw can also be used to hold the saw in such a position that the teeth are above the vertical wall of the base so that the teeth may be sharpened by the ordinary file.

Saws are usually jointed by running a fiat file over the teeth. In my improved device, the saw is placed in the space between the vertical wall of the base and the vertical wall of the extending portion 45. The saw is then drawn back and forth over the file to accomplish the desired results.

What I claim is:

In a saw jointing device, the combination with a flat horizontal base having a vertical wall rising from one edge thereof, of a first plate extending horizontally from said vertical wall outwardly of the base, a return bend at the outer end of said plate, a second plate extending from the return bend toward the wall spaced above and parallel with the first plate, said first and second plates and return bend forming an approximately U-shaped structure, a third plate rising vertically from the inner end of the second plate spaced from and parallel with the outer face of the wall to provide a saw guide slot, a screw threaded horizontally through an opening in the third plate, and a screw threaded vertically through the second horizontal plate for clamping a file between said first and second plates.
